Publisher Microsoft Game Studios is holding a one-day sale today for five of its most popular titles on Xbox Live Arcade, slashing their usual prices of 1200 MS Points ($15) to 600 MS Points ($7.50).

The special sale includes Playdead Studios' Independent Games Festival award winner Limbo, RedLynx's Trials HD, The Behemoth's Castle Crashers, Chair Entertainment's Shadow Complex, and Uber Entertainment's Monday Night Combat.

If you've gone this long not buying any of these well-received games, today's the day to snatch them up -- they'll go back up in price tomorrow.
